#28 is fantastic!!! It has my favorite overall layout. I love the three-dimensional look! The red stars are the only thing I'm not certain of. "Crystal" white, silver, or blue seem like they would be more magical.
The idea of a circular globe in #30 is really good, but right now I still like the square approach better although this might change.
#31 is a great look with a dark background.
#29 is a good vertical layout which I would ultimately like to also have in addition to the main logo design. I'd love to see more variations of this eventually.
I don't have access to that forum thread but I have a general idea why you had to remove them.
#34 looks really great! Actually a butterfly is a better symbol for transformation than a tree for growth so I'm very happy with this design too. I really like the streaks across the top too!
I'm not sure about the butterfly shape and color, though. Perhaps a few variations of it? White? Blue? Orange? Yellow? The green just seems a bit dark... perhaps a bright green?
The only thing I don't like about #32 and #33 is that the leafs look like they are growing right out of the body which seems a bit odd for me.
I like the stars in #32 but I think they are better placed in #34.
#39 is awesome but #40 blows me away! That is such a cool design! I LOVE IT!!
I just noticed #41... I love the placement of it as well! All three of these are awesome... #39, #40, and #41. I think I like #41 just a little bit better.
